Well I have a very similar problem:
We are running Imail as our mail gateway and after installing win2k sp1
(full) and a minor upgrade, a few of m users stopped receiving emails. The
can send but not receive. The get error message 0x800ccc19: their connection
times out.
Everybody else is running fine, these machines are running XP pro and
Outlook 2k and one of them win98 and OE. The XP machines connect to us via
an IPSec tunnel and the win98 via pptp. I know you'll say: well, look at
your firewall, I have not YET just because we have 20 other remote users via
pptp that don't have the problem. I will today.
I turned on logging for Outlook on the xp machines and what I get is:

I'm starting to think that this is related to an OS issue/bug triggered by
an implementation made by my email server and not a server issue. I know
it's related to sp1 because this is the second time it happened and I was
forced to uninstall it and everthing went back to normal.
My email log says the user logged on/off successfully w/no errors.
I don't want to uninstall sp1 because I think that's not the solution.
Any suggestions would be helpful.
thanks
